Generally, when a window is constructed, the door is fixed to the door frame in a state where the door frame is fixed first. However, the door frame may be erroneously applied during installation or installation, or after the door frame is pressed against the building wall load, A gap may be formed between the door frames. In such a case, there is a problem in that the work time and manpower consumption are increased when the door frame or the window itself is separated and reconnected.

Therefore, in order to easily solve the gap between the door frame and the window, the height of the roller installed on the window racket can be raised and lowered by the adjusting screw, so that the height of the roller of the racket can be easily adjusted So that it can be solved.

The window car is installed at the lower part of the sliding window so that the roller is rotated on the rail of the door frame so that the window can be opened and closed smoothly.

An adjusting screw is fastened to one side of the outer case, and an end of the adjusting screw is screwed to a hole of the inner case installed in the inner case.

Therefore, when the adjusting screw is rotated, the adjusting screw is rotated in place so as not to be pulled out by the holder, which is a separate component, and only the inner case is moved in the left and right direction according to the rotating direction of the adjusting screw, The rollers installed in the case are raised or lowered by the vertical ball and the inclined slot, and their height is adjusted.

However, in the conventional window carriage, since the holder, which is a separate component, is necessarily installed in order to rotate the adjusting screw in place so as to prevent the adjusting screw from being pulled out when assembling the outer case and the adjusting screw, the assembling work is inconvenient, And productivity is deteriorated.

In addition, in the conventional window carriage, there is no stopper structure for stopping the movement of the inner case when the roller is lifted up to the maximum, and the adjustment screw is kept screwed to the hole of the inner case When the operator turns the adjusting screw forcibly in this state because the screw does not idle, the adjusting screw and the inner and outer case and the rivet are subjected to excessive force. Especially, when the excessive force is applied, There has been a problem in that it is flared or deformed.

In addition, in the conventional window racing car, since the lower portion of the outer case is completely opened, the outer appearance of the outer case is not so good, and foreign matter such as dust or dust generated during driving of the roller easily flows into the outer case there was.

On the other hand, in the Korean Patent Utility Model No. 20-0188830, the holder is not used as a separate component for rotating the adjusting screw in place so as to prevent the adjusting screw from falling when the outer case and the adjusting screw are assembled, And the lower screw hole is formed into a small screw hole and the screw is inserted into the upper screw hole so that the screw is lowered so that the groove of the screw is inserted into the lower screw hole. There is a problem in that the adjusting screw can not be firmly assembled because the fitted adjusting screw flows upward.
